压电光电效应是关于使用压电半导体材料中存在的压电极化电荷来增强光生载流子的分离、传输和复合。在这里，它是提出，压电光电效应可以有效地应用于提高相对转换效率的柔性太阳能电池的基础上的n-ZnO/p-SnS核壳纳米线阵列为37.3%，在适当的垂直压力。通过对器件的轻微弯曲，可以有效地提高太阳能电池的性能，显示出其在卷曲几何形状中的应用潜力。本研究不仅加深了对压电光电效应提高太阳能转换效率的认识，而且展示了压电光电效应在大规模、柔性、轻量化纳米线阵列太阳能电池应用中的巨大潜力。
The piezo-phototronic effect is about the enhanced separation, transport, and recombination of the photogenerated carriers using the piezoelectric polarization charges present in piezoelectric-semiconductor materials. Here, it is presented that the piezo-phototronic effect can be effectively applied to improve the relative conversion efficiency of a flexible solar cell based on n-ZnO/p-SnS core-shell nanowire array for 37.3% under a moderate vertical pressure. The performance of the solar cell can be effectively enhanced by a gentle bending of the device, showing its potential for application in curly geometries. This study not only adds further understanding about the concept of increasing solar energy conversion efficiency via piezo-phototronic effect, but also demonstrates the great potential of piezo-phototronic effect in the application of large-scale, flexible, and lightweight nanowire array solar cells.
